This pin passes through the'slot'Ql inthe manner show-n in Figure Il. flt'is evident thatiby rotatingr'the piln'abou't theaxis otk the valve 'stemwitiivill be eaused toffmovel upwardly or downwardly, as' the `ease maybe therebyA raising ,or loweringf the valve so vas to control they admission of gas to the interior o'l' Ithe burner 18. Burner 12 constructed; irnfexactly the same manner asfwburner 13, but is not provided Within valveA or With a lvalve controlled mechanism. The. ends of theomanifold are closed by'means of cup-shaped plugs 23.

Referring; now more particularly toligure ouv a it vvill be notieed'that ironv straps Qlhave one-end bent into a@ Ushaped torrnation'in the manner shoivnand indicated by `reference numeral '25. 'The sioes of this llll-shaped portion are providedwvith shoulders Qo-Jtliat yserve as supports for the longitLrd-inal ribs 27A of the manifolch which lare connected to `the shoulders byfvbeing-spotwvelded1thereto- 'The eXtreme-endof the strap Q4 has .been

EFromf 105 the inclined portion 29,the straps extend this portionthey are curved in the are `otl@ a circle which curved portion has been indicated by numeral 33, and the extreme end is bent reversel in the manner indicated by numeral 34. i n arcuate strap 35 has its straight end 36 secured to the end 34 by means of a rivet 37 and has its other end connected to the strap 24, between sections 32 and 33, by means of a bolt 38. From the above it will be seen that the tank is rigidly attached to the manifold and burners by means of the two straps 24. The manifold 14 is provided with an opening 39 at a point substantially half way between the two burners. A bearing member 40 is electrowelded to the upturned flange 41 of the manifold and has the lower portion 42 flared outwardly in the manner shown in Figure 7. A curved tubular member 43 is provided near its end with a shoulder 44 which engages a similar shoulder on the bearing member 40, and has its eXtreme end expanded as indicated at 45 so as to lit against the inner surface of the conical portion 42. The pipe 43 is rotatably connected to the manifold by the means just described and shown in Figure 7.

The tubular member or pipe 43 is curved through an arc of ninety degrees and is there provided with a downwardly extending opening 46 which terminates a short distance above the upper surface of the man1- fold.

Located directly above the burner 12 is a generator 47 whose end projects into the horizontal end portion of the tubular member 43 when the parts are located in the manner shown in Figure 2, where the upper portion of the horizontal part of tubular member 43 has been broken away to show the yposition of the end of the generator 47.

This generator is connected tothe tank 48 by means of a pipe 49 and a valve member 50, in the manner shown in Figures 1 and 2. VThe valve 50 has a hand wheel 51 by means of which it can be moved from open to closed position and vice versa.

Extending laterally from the horizontal portion of the tubular member 43 is a channel 52, to the end of which a spout 53 is secured. One end of this spout is entirely enclosed in the manner indicated by numeral 54. By rotating the tubular member 43 in the bearing by which it is connected to the manifold, it can be moved from the position shown in Figure 2 to the position shown in Figure 1 and vice versa.

In the operation of the stove, the gasoline is contained in the tank 48 and is subjected to a moderate pressure by means of air which is forced into the tank by the pump 55. V'Vhen the valve 50 is open, gasoline from the tank will flow through the pipe 49 and through the generator 47. Before the stove will operate properly, this gasoline must be converted into vapor by means of heat and it is therefore necessary to heat the generator 47 to such a temperature that it will vaporize the gasoline as it flows through it.

For the purpose of heating the manifold, it is necessary to fill the priming cup 56 with gasoline, which is then ignited. In starting the stove therefore, the pipe 43 is rotated in a counterclockwise direction from the position shown in Figure 2, to the position shown in Figure 1, in which position the gasoline that issues from the end of the generator 47 will strike the closed end of the part 54 and will flow through the trough 53 into the priming cup 56. Then the priming cup has been filled with gasoline, the valve 50 is closed; the tubular meinber 43 is moved back into the position shown in Figure 2 and the gasoline in the priming cup is then ignited. lVhen the gasoline in the priming cup has been nearly consumed, th-e valve 50 is again open and the gasoline which now flows through the generator will issue in the form of vapor which will pass into the tubular member 43 where it will become mixed with air sucked in through the opening 46. rIhis mixture of air and vapor will then pass through the manifold into the burner 12 and emerge through the perforations in this burner, when it will ignite and the heat from the burning gas will continue to keep the generator of suflicient temperature to vaporize the gasoline.

If one burner'only is desired, the valve 17 may be retained in closed position; but if two burners are needed, the valve 17 is opened and part of the gas will then flow into burner 13 and can be ignited. For the purpose of opening and closing the valve 17, I have provided a slide 57, which is attach-ed to the straight portion of the strap 24 that corresponds to the burner 13. This slide member has a downwardly projecting side 58, whose end is provided with an opening 59 to which one end of the connector 60 is connected. The other` end of this connector is bent at right angles in the manner indicated by reference numeral (S1 and this end projects through an opening in the pin 22. The side 58 is also provided with another opening 62, which receives th-e end 63 (Fig. 8) of the wire 64 whose outer end 65 extends over the top of the gasoline tank 48. A clip G6 has one end electro-welded to the side 68 and has the end portion 67 offset and projecting upwardly above the end 63 so as to hold it from outward movement. A clip 68 is attached to the strap 24 and encloses the wire 64 in the manner shown in Figures 2 and 4. It will now be apparent that when the wire 65 is pulled to the left in Figure 4, it will rotate the pin 22 in the helical slot 21 and cause it to move upwardly, thereby opening the valve 17. And when it is moved towards the right, it

will close the valve. By this means, .therefore, the escape of gas through the burner 13 can be regulated and entirely prev-ented if desired.

When the stove is to be used the parts are moved to the position shown in Figures 2, 8 and 4l, in which position the tank i8 is located on the outside of the wall 3, and the burners 12 and 13 are located directly beneath the grates 10. The end 2 is provided with a notch 69 which receives the part of the valve indicated by numeral 70.

After the stove has been used and when it is desired to transport it, the parts are moved to the position shown iii Figure l, where the tank burners and valves are all enclosed within the casing. When the parts are assembled as shown in Figure l, the cover 1 1 can be closed and the entire stove will then be in a very compact form, which is convenient for handling and in which the operative parts are protected against injury.

Having now described the invention what is claiinetl as new is:
